CADRE Evaluation (Area code 71) for consideration as part of the Idaho 

Chemical Processing Plant Special Exposure Cohort 

Timothy D. Taulbee, PhD, CHP

Introduction

Sanford Cohen and Associates (SC&A) recommended that persons with dosimetry indicating CADRE 

should be considered part of the class of workers at CPP. 

“Observation 4: Absent additional information to the contrary, dosimetry associated with “CADRE” 

should be considered CPP for the purposes of determining SEC eligibility. Similar to the CPP dosimetry 

records, it is important to establish that “CADRE” badging records have all been captured from INL.”

This was based on a listing of area codes in which Area Code 71 was inadvertently listed as being at CPP.

Discussion

Throughout the SL-1 documentation and prior to the accident, CADRE appears to reference the military 

staff that operated the reactor. Photos #59-4107 and #59-4108 are titled “View of Cadre at SL-1”. Later 

in 1959, photo 59-6570 is titled a “Special operator’s course number 1 at the SL-1 Cadre U.S. Army 

Engineer Reactors group.” In 1960, photo #60-3918 appears to be a photo of the group at the CADRE 

training building located at the Stationary Low Power Reactor (SL-1), which is consistent with the 1959 

photos indicating a reference to personnel and training.

In 1962, 1963 and 1966 the area dosimetry reports for Area Code 71 list CADRE as the “contractor” 

however the location is listed as ERC (Figure 1). This documentation is the original forms to the 

information SC&A found on the locator cards for certain individuals. 

 

In 1962, the photograph index acronym list indicates ERC is the Emergency Response Center. The focus 

of the 1962 photo set appears to be from the AEC Security Division evaluating potential offsite locations 

in Rexburg (nearby town) for the Emergency Response Center. 

An investigation of the individuals listed on the CADRE dosimetry reports for 1962, 1963, and 1966

revealed that Site Mangers and a very large number of Division Directors or Chiefs are included on this 

dosimetry report (Attachment A). The Division Directors or Division Chiefs names and affiliations were 

found in the 1960 Health and Safety Annual Report internal distribution list (SRDB 8078). In addition, 

some of the individuals on the CADRE dosimetry report were Health and Safety personnel as well as 

security, communications, and meteorologist. All of the job titles found are consistent with a staff 

expected at an Emergency Response Center during an off normal occurrence. 

In 1965, Emergency Response Center (ERC) is again found in the photo index indicating that the Offsite 

ERC was at the I.D Headquarters Building in Idaho Falls. 

Conclusions

NIOSH believes that with this follow-up there is sufficient evidence to the contrary that CADRE was in 

reference to the staff at the Emergency Response Center (ERC) in the early 1960’s. We believe the initial 

indication in the area code table is not correct and therefore should not be considered part of the CPP 

SEC class.
